UPDATE
In an exclusive conversation with the man driving directly behind Brandy at the time of her fateful crash, TMZ has learned that the singer repeatedly blamed herself at the scene of the accident.
"She got upset, talking about how it was all her fault ... she didn't stop, kept saying how she hit the lady," says the witness.
He added, "Brandy walked in front of traffic, crossing the lanes of speeding cars, then she did it again. People were honking at her to get out of the road. She was obviously disoriented and highly upset."
The witness also claims he tried to calm the hysterical singer, and even dished out some legal advice, saying he advised her to stop admitting guilt. He also consoled her by repeatedly saying "It was an accident."
The witness also claims he went over to check on the woman in the Toyota, but couldn't find a pulse.
Brandy was not injured. The driver of the Acura suffered moderate injuries.
Brandy was not arrested and there is no evidence drugs or alcohol were involved.
Police are doing a mechanical investigation of the cars involved in the accident to determine if there was a malfunction.
Brandy's "Moesha" co-star, Lamont Bentley, was killed in January, 2005 when his car plunged off the same freeway. Another "Moesha" co-star, Merlin Santana, was killed by a gunshot wound while sitting in the passenger seat of a car in 2002.
